In this first-hand account, John Volanthen reveals how he pushed the limits of human endurance in the life-or-death mission to rescue the Thai youth soccer team trapped in the flooded cave. The world held its breath in 2018 when the Wild Boars soccer team and their coach went missing deep underground in the Tham Luang cave complex in northern Thailand. They had been stranded by sudden, continuous monsoon rains while exploring the caves after practice. With torrential rain pouring down and the waters still on the rise, an army of rescue teams and equipment was deployed, including Thai Navy SEALs, a US Air Force special tactics squadron, police sniffer dogs, drones and robots. But it was British cave diver John Volanthen and his partner, Rick Stanton, who were first to reach the stranded team and who played a key role in their ultimate rescue. Each chapter of Thirteen Lessons that Saved Thirteen Lives tells one part of the edge-of-your-seat mission from Tham Luang but also imparts a life lesson, gleaned from John's previous rescues and record-breaking cave dives, that can be applied to everyday obstacles and challenges.
